The PGP desktops exported secret keys are really stupid. And they

out (section 11.2):
[...] Implementations SHOULD include self-signatures on any user
IDs and subkeys, as this allows for a complete public key to be
automatically extracted from the transferable secret key.
Implementations MAY choose to omit the self-signatures, especially
if a transferable public key accompanies the transferable secret
key.
Now if they would only put the public key before the secret
key. Anyway we now have a workaround for that ugliness.

When importing an invalid secret key ring for example without key
binding signatures or no UIDs, gpg used to let gpg-agent store the
secret keys anyway. This is clearly a bug because the diagnostics
before claimed that for example the subkeys have been skipped.
Importing the secret key parameters then anyway is surprising in
particular because a gpg -k does not show the key. After importing
the public key the secret keys suddenly showed up.
This changes the behaviour of

(get_best_pubkey_byname): Add support to refresh expired keys from the

--
A little drawback of that code is that if the WKD has no update for an
expired key each access of the key will trigger a WKD lookup (unless
cached by the dirmngr). To avoid this we need to record the last time
we have checked for an update but that would in turn require that we
update the keyring for each check. We defer this until we have a
better key database which allows for fast updates of meta data.
Testing the code is currently a bit cumbersome because it requires to
update a key in the WKD several times. Eventually we we need a
network emulation layer to provide sample data for the regression
tests.

* g10/key-check.c (sig_comparison): Take care of HELP_COUNTER.
(key_check_all_keysigs): De-duplicate on a per-block base.
--
The key_check_all_keysigs first does a detection of duplicate
signature. This is done over all signatures at once. The problem
here is for example:
key
uid_1
sig_uid_1.1
sig_uid_1.2
subkey_1
sig_sub_1.1
subkey_2
sig_sub_2.1
sig_sub_2.2 (duplicate of sig_sub_1.1)
Now the de-duplication deletes the first signature and keeps the
second. That works in most cases for foreign signature on userids but
in the above constellation the code simply removes sig_sub_1.1 so that
subkey_1 has no binding signature anymore. In a later step during
import the missing binding is detected and subkey_1 is removed because
it is not anymore valid. The sig_sub_2.2 will also be removed later
because it does not check out for subkey_2 (that is as expected).
The fix is to let the de-duplication work only on blocks (ie. within
the signatures of a user id or a subkey). This will not detect all
duplicates but that does not harm because later steps will detect and
remove them.
In the above case (with this patch applied) the second phase of
key_check_all_keysigs will reorder key signatures and move the
duplicate sig_sub_2.2 directly after sig_sub_1.1. This duplicates the
signature and for cleanness we should kick the de-duplication process
again. This will be done with a followup patch.

This fixes an actual regression in GPGME where FAILURE is considered

In particular for files with more than one signature a log_error if
often called to show that a pubkey is missing for one of the
signatures. Using that log_error is correct in that case.

--
This fixes a bug in writing a zero length last chunk right before the
final chunk (which has by design a zero length). We also need to
adjust the decryption part because that assumed this zero length last
chunk.
Note that we use the term "last chunk" for the chunk which directly
precedes the "final chunk" which ends the entire encryption.

GnuPG-bug-id: 3774
This fixes the reported case when the encrypted data is a multiple of
the chunk size. Then the chunk index for the final chunk was wrongly
incremented by 2. The actual fix makes use of the fact that the
current dfx->CHUNKLEN is 0 in this case. There is also some other
reorganizing to help with debugging. The thing seems to work now but
the code is not very clean - should be reworked. Creating test files
can be done with this script:
--8<---------------cut here---------------start------------->8---
csize=6
for len in 0 55 56 57; do
awk </dev/null -v i=$len 'BEGIN{while(i){i--;printf"~"}}' \
| gpg --no-options -v --rfc4880bis --batch --passphrase "abc" \
--s2k-count 1025 --s2k-digest-algo sha256 -z0 \
--force-aead --aead-algo eax --cipher aes -a \
--chunk-size $csize -c >symenc-aead-eax-c$csize-$len.asc
done
--8<---------------cut here---------------end--------------->8---
A LEN of 56 triggered the bug which can be seen by looking at the
"authdata:" line in the --debug=crypt,filter output.

This code has seen only a very few manual tests. Encrypting always
uses a 64k chunks and decryption has not been tested with larger
chunks. Those small chunks make debugging much faster.
Tests can be done using:
gpg --rfc4880bis --pinentry-mode=loopback --passphrase abc \
--force-aead --aead-algo ocb --s2k-mode 0 --cipher AES \
-v -z 0 --status-fd 2 -c <INFILE >OUTFILE

--status-fd 2 -v -d <INFILE >OUTFILE

(parse_algo_usage_expire): Pass the parsed USAGESTR to
parse_key_parameter_string so that it can use it in case a subkey is
to be created.
--
The problem here was that future-default gives the primary and subkey
algorithm. However, when using future-default for adding a key, the
second part was always used which is for encryption. If the caller
now wanted to create a signing subkey using the future-default
parameters this did not worked.
gpg --batch --passphrase "" --quick-add-key FPR future-default encr
aready worked as did
gpg --batch --passphrase "" --quick-add-key FPR ed25519 sign
but
gpg --batch --passphrase "" --quick-add-key FPR future-default sign
does only work with this fix.
